of the threads on the wheel or hub 301mm 3. nousLEY', or LOS To all whom it may concern:

"Be it known that I, ROBERT B. HOUSLEY, a citizen of the United States, residing at Los Angele s,-in' the county of Los 'Angeles andState-of California, have invented a new and useful VVheel-Hub, of which the following is a specification.

- This invention relates to improvements in hubs for wheels and more hub cap. l

In demountable wheels inwhich the hub particularly to a cap is threaded upon the hub and serves as an element to assist in the retention of the Wheel uponthehub, the screw-threads are often rupturedor crossthreaded when the hub cap is carelessly or too rapidlyturned upon the hub. This too rapid and careless'turning of the hub cap is often occasioned in making a quick Wheel change.

My invention obviates the cross-threading cap and permits of aquick wheel change Without liability "of injury to the screw-threads and resultant permanent damage tethe -wheel as a"wl1ole and consists in theprovision of a itwhileit is being turned or theaded upon the hub, such means adapted to seat'against the huband acting :to center the cap so as to insure a perfect alinement ofthe screwthreads. I

Other objects and advantages will appear in the course of the following description.

The accompanying drawings illustrate the invention:

Figure 1 is a sectional view taken through a demountable wheel showing the hub thereof broken away and in section and my hub cap in positionthereon.

Figw-B is a front elevation of'the hub cap.

Fig. '3 is a vertical sectional view of the hub cap; and

Fig. 4 is an inside face elevation of the hub cap. a

Referring to the drawings, 1 designates as an entirety a demountable Wheel comprising a hub 2, spokes 3, rim 4 and tire 5. In this t pe of wheel, the axle 6 extends through he hub and a nut 7 turned upon the outer end of the axle abuts an annular shoulder *8 formed on the hub. The shoulder 8 is formed by coring the outer end of the hub a lld said outer end is exteriorly screw- WHEEL-HUB.

threaded at 9 to cooperate with the screwthreads on the hub .cap, which will be later more fully described. A hub casing 10 sun-,2 rounds thehub 2 and the hub cap is adapted; to be wedged between the casing and hub:

so as to hold the Wheel. in position. The hub isprovided with a flange 11 which iscon-a nected with the hub casing by a suitable means 12. a r j.

. My improved hub cap 13 comprises cylindrical body portion :14 which ;is formed:

with an annular recess or groove 15 opening upon'its inner: face. The forming of this recess 15 I provides a cylindrical projection;

16 which serves as a guide means in turning the cap upon the hub and 'saidprojection extends beyond the adjacent edge of.the cap a slight. distance, for example, one-sixteenth.

of an inch, so as to engage in the cored outer portion of the hub 2 prior to 1t e contact of the adjacent edge of the'ca with. the hub. The outer annular face of the recess 15 is provided with screw-threads 17 adapt ed to cooperate withthe screw-threadsfironr the hub-Zand said screw threads terminate at a point spaced from the iinner end of the. recessso that when :the capv is screwedupon the hub, the latter will be spaced from the inner end of the recess. The outergface of; the hub is reduced to providea hexagonal portion 18 adapted to ,be grasped by a;

Wrench to eflect the removal or placement of the cap upon the wheel. The periphery of. the hub adjacent the inner side thereof is tapered inwardly as at 19 so as to effect a Wedge between the hub casing 10 andhub 2, as shown in Fig. 1 of the drawings.

In operation, to secure the cap upon the wheel, the cylindrical guide projection 16 is inserted'in the cored outer end of the hub 2' and since it is of a diameter slightly less than that of the inside diameter of the cored portion of the hub, it will act as a centerin and guiding means for the cap and permit of its being turned rapidly and accurately into position. This projection 16 has a bearing upon the inner face of the cored portion of the hub and causes the screw-threads 1'1" and 9 to cooperate With each other properly and effect a secure fastening of the hub with- .out any possibility of cross threading. It

often occurs in making a quick change on racing cars, and other cars as Well, that the i possibility 1 end, of

:aeefaeee wrench used to remove the cap is allowed to remain upon the 'cap so that when the new wrench instead of by hand and in giving a" start with a wrench it is turned rapidly and often inaccurately, causing the threads to be ruptured or crossed. With .my hub cap all guiding means provided by the cylindrical projection 16. v I claim:

1. An interiially;screw-threaded hub cap having a cylindrical smooth-faced projection located Within the cap in circumferentially spaced relation to the screw-threads 2;."An internally screw-threaded hub cap having a cylindrical projection located inside of the flange of the cap in circumferentially spaced relation to the screw-threads thereon and projecting beyond the inner side of the hub cap.

3. The combination with a vehicle hub having .upon' the screw-threads and having internal 1 screw-threads therein,

serve as a guide during cap upon the hub. 40

and a guide means 'havin'g a'smooth hub-engaging face mounted upon the hub cap to engage the interior of the hub.

4. hub cap comprising an internally screw-threaded body, and means interiorly of "the body and spaced circumferentially from the screw-threaded -'portion thereof adapted to engage the interior of a-hub and the turning of the 5. The combination with a demountable wheel including a hub having external s'crew-threads'upon its outer end, of armssu'rrounding and secured to the hub, a
